would gnd engineer,atc or fire crew hve been the first to inform the flt deck.
at that point i doubt the flt deck would hve known the no. of pax still on board,the severity of the fire or the likely outcome of its containment.with only one aero-bridge connected it would take several minutes to de-plane.why did htey not initate an evac.considering the large unknowns in those forst few seconds?
im aware the apron can be a chaotic place with vehicles and loaders etc.but this is a fire of unknown quantity,not a propable containment case such as an apu where a fire handle could be pulled.
i believe it took a couple of mins for the fire crew to arrive.a long time in which a full evac could hve been carried out.i doubt all the pax could hve been deplaned from the aero-bridge exit in that time while the fire was still going?
